Liberal Democrat councillors are preparing to revolt over the coalition government's crackdown on solar subsidies, as a growing number have been greeted with stiff opposition from outraged householders and companies fearing swingeing job cuts.

A secret briefing document seen by the Guardian reveals the extent of Lib Dem anger at the controversial policy to slash solar power incentives for households - a policy that many local Lib Dem politicians feel is a betrayal of their core values. Local councillors are being advised to push for a postponement of the subsidy cuts, as a minimum.
